Cisco 971 and two Windows 2000 Server Subnets Routing Problem

Hi Experts,
I am using a Cisco 871 router to interface between 2 subnets as follows:
VLAN1 : 10.10.10.0/29 on fe1(10.10.10.1) : Used for Router administration only

VLAN2:  192.168.0.0/24 on fe0 (192.168.0.253):  Subnet 1 - Administration Subnet
The Administration Subnet has a Windows 2000 Server (192.168.0.2) - ADMIN1-with 1 NIC.  This server connects to the internet via a 3COM Router.

VLAN3:  192.168.16.0/24 on fe2(192.168.16.253): subnet 2 - Labs Subnet.
The LABS Subnet also has a Windows 2000 server (192.168.16.2) - LABS1-with 2 NICs. This server acts as the internet Router for the Labs Subnet via RRAS.

fe4 on the Router is disabled.
.
From within the Router (via telnet) I can ping fe0,fe2, ADMIN1, LABS1). Each Server can ping it's respective port on the Router but not each other!
 The running config for the Router is below.  If I connect 2 PCs to the respective ports, they can ping one another - but not the servers!  Therefore I am assuming that a routing problem existis on the servers.
I added a static route to the LABS server (192.168.0.0 255.255.255.255 192.168.0.253) but this did not work ( I know I forgot the metric).
All suggestions welcome. Thank you for your help.  

!This is the running config of the router: 10.10.10.1

Basically, wherever you have a client or server whose default gateway is not the cisco router, then you are going to have to add a static route on the windows machine that routes those network segments.

For example, on the ADMIN1, you would need the following:
route add 192.168.16.0 mask 255.255.255.0 192.168.16.253
Sounds like you already have your route statement on the LABS server:
route add 192.168.0.0 mask 255.255.255.0 192.168.0.253

Once that is setup, you should be able to ping between the servers as a test.  You will have to add routes to each workstation also that doesn't point to the cisco router as the default gateway.

Thank you craigothy.  
I'll add the static routes to the servers ths  morning and let you know how it works out.
Each subnet has it's own respective DHCP server that points to it's own respective default gateway
for internet access.
  I'm assuming that the static routes setup on each server will handle inter-subnet communications.

Hi Craigorthy

Our School was closed for Easter and re-opned today.  So I could only add the static routes until today
I regret the delay in responding to you.

 I can ping the router from either server. I can ping the respective gateway from eirhter server but I still cannot ping one server from the other.  My ping results are below.

If I conect the router between 2 PCs, set static ips from both subnets on both and add a static route on both, I can ping each PC respectively.  I am therefore convinced that I have a routing problem on the servers.  Your advice would be welsomce. Thanks for your help to date

Can you post the results of the "route print" command from each server?

Hi Croadorthy,
routinh was incorrect pn Labs server.  Once corrected, the system works fine now

Thanks for all your h
